Hi Modak,
Thanks for your quick reply.
The issue is when reviewer click on "Send for approval" button immediately step type activity should trigger.
The approver will receive a workitem similar to reviewer workitem, but approver will get Approve and Reject button.
Reviewer will recieve the workitem with send for approval button.
Business object coding part is done. I am not doing an SOFM attachment.
Approver determination logic is already done and it is working fine.
Conclusion: When I click a send for approval button It should start a activity step, if this is done my problem will be resolve.
Thanks,
Siraj.
